David Lee, whose last role was in 2012 in Gu Family Book, will play Park Min Joon, an honor student at Segang High School. He was born to study, and his peers call him the "Study Robot." He will play a rival to Kim So Hyun's character Eun Byul.

In School 2015, Kim So Hyun plays dual roles as identical girls: one who is the queen of the school until her disappearance, and the other, a transfer student who takes her place in the school hierarchy.
